## How to Use the Matrix Multiplication Calculator?

### Input the First Matrix

Begin by entering the elements of the first matrix. You will find fields corresponding to its rows and columns. Make sure you enter the elements according to its actual dimensions. For instance, if your first matrix is 2x3, there should be two rows and three columns filled in.

### Enter the Second Matrix

Now, enter the elements of the second matrix. It's critical to note that the number of rows in this second one should match the number of columns in the first one. This is because, in matrix multiplication, each element in the first matrix's row must pair with a corresponding element in the second matrix's column.

### Click "Calculate"

Once you have entered both matrices accurately, click the "Calculate" button. The calculator will swiftly perform the matrix multiplication and display the result.

### Review the Result

After the calculator completes the multiplication, you will see the resultant matrix, often referred to as matrix $$$C$$$. This new matrix is the product of the multiplication of the first matrix and the second matrix.

## What Is Matrix Multiplication?

Matrix multiplication involves combining two matrices to generate a new matrix. Unlike regular multiplication, it involves the sum of the products of corresponding elements from rows of the first matrix and columns of the second one. The mathematical formula for matrix multiplication, given a $$$m\times n$$$ matrix $$$A=\left[a_{ij}\right]$$$ and a $$$n\times k$$$ matrix $$$B=\left[b_{ij}\right]$$$, is as follows:

$$c_{ij}=\sum_{s=1}^n a_{is}b_{sj}$$Here, $$$c_{ij}$$$ is the element of the new matrix, matrix $$$C$$$, resulting from the multiplication.

## Sample Matrix Multiplication

Consider two matrices, $$$A$$$ and $$$B$$$, where $$$A$$$ is a 2x3 matrix and $$$B$$$ is a 3x2 matrix.

Matrix $$$A=\left[\begin{array}{ccc}1&2&3\\4&5&6\end{array}\right]$$$.

Matrix $$$B=\left[\begin{array}{cc}7&8\\9&10\\11&12\end{array}\right]$$$.

By multiplying these two matrices, we get:

$$C=AB=\left[\begin{array}{ccc}1&2&3\\4&5&6\end{array}\right]\left[\begin{array}{cc}7&8\\9&10\\11&12\end{array}\right]=\left[\begin{array}{cc}1\cdot 7+2\cdot 9+3\cdot 11&1\cdot 8+2\cdot 10+3\cdot 12\\4\cdot 7+5\cdot 9+6\cdot 11&4\cdot 8+5\cdot 10+6\cdot 12\end{array}\right]=\left[\begin{array}{cc}58&64\\139&154\end{array}\right]$$## Why Choose Our Matrix Multiplication Calculator?
